RAM refresh rate.

Is it possible to lower the DRAM refresh rate on the Raspberry Pi ?

I heard that it's possible for other desktop linux distros to tweak the DRAM refresh rate in order to boost system performance, done through a /proc file ( I think )
But, is it possible with the Pi ?

AFAIK, lowering DRAM refresh rate would lower power consumption. How would it increase system performance?

[nickon314]

My understanding is the processor is locked out while the RAM is refreshing, so less frequent refreshes means more time for the CPU to use the RAM.
Which, in theory, means a more responsive system.

I remember that there was some special DOS magic that I used many years ago to affect the RAM refresh rate. So, I know it's possible.
Or, maybe it was a bios setting. I can't quite remember.
